JOHN LYLE, OF NEWARK, NET JERSEY.

Letters Patent No. 96,453, dated Nominee 2,1869.

IMPROVEMENT IN LEATHER-PUNCHES.

The Schedule vreferred. to in these Letter-s Patent and making partvof the seme.

of various sizes, u'ramged. on au adjustable hub, con-l nerted to one end oi' one of the jaws; and

The invention consists in an improved arrangement of the hub for connection with thel said jaw, whereby it is held more securely in position, against the tendency to turn when punched.

Figure l represents a. side elevation of my improved punch; and

Figure 2 lcpre'sents an end view, showing the hub, and the end of the jaw to -which itis connected.

Similar letters of reference indicate corresponding paris.

The jaws A- B are the same as those of ordinary construction, except that the end of' the jaw B is made rectangular in cross-section, and is bent near the joint O, so as not to be in the same plane with the other jaw.

D 'is the hub, whereon the punches are mounted radially.

It is mounted:A axially on a. pivot thumb-screw, E, screwing into the said hub, and passing through the jaw transversely, as shown in the drawings.

This hub is provided, on the face which bears against the jaw, with stud-projections F, as many as there are punches, and so arranged in position, relatively to the punches, and -in respect of distance -from each other,

that when clamped upon the jaw B, for any one ofthe punches to actnpon the die G, four of the said studprojections will bear against the edges of the said jaw', two on one edge, and two on the other, so as to wholly prevent any movement of the hub on its axis, and to effect the sa'me without-` unduly straining any ot' the parts, holding the punches as rigidly as when only one punch is permanently connected to its jaw.

' The thumb-screw is unscrewed for adjusting. the

Having thus described my invention,

Patent-'- .l

Tile combination, with the jaws A B, of the hub D 'and thumb-screw E, when the said hubis provided as specified.
